Title: Laminated capacitor
Inventor: MIZUNO YOICHI
IPC: H01G4/30
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a laminated capacitor which has a low capacitance, a high Q-value, and no internal structural defect. SOLUTION: Electrode pairs 26, each of which is constituted by arranging two internal electrodes 22 connected to one external electrode 24 in parallel with each other with a dielectric layer in between, and electrode pairs, each of which is constituted by arranging two internal electrodes 22 connected to another external electrode 24 in parallel each other with a dielectric layer 25 in between, are alternately laminated upon another with dielectric layers 21 in between. In addition, the dielectric constant ε1 of the dielectric substance used for forming the layers 25 is set at a value higher than the dielectric constant ε2 of the dielectric substance used for forming the layers 21 (ε1>ε2). Therefore, a high Q-value can be obtained in a high-frequency region and, at the same time, the internal stress strain of a laminated capacitor can be dispersed, because the eddy current losses which occur in the internal electrodes 22 become smaller and the resistance of each internal electrode piece can be set at a low value. In addition, the occurrence of a structural defect, such as the crack, delamination, etc., can be prevented.

Title: Measuring method of heating temperature of member to be treated in high-frequency heating
Inventor: ISHIDA MITSUMASA
IPC: G01J5/08
Filed: 1984-11-29
Abstract: PURPOSE:To heat surely a member to be treated having a step to an adequate temp. for hardening and to improve hardening quality in the stage of hardening said member by heating with a high-frequency heating coil by measuring directly the temp. in the fillet part of the member to be treated with a temp. measuring element consisting of an optical fiber. CONSTITUTION:The high-frequency heating coil 2 is disposed to enclose the member to be treated having the step and high-frequency current is passed to heat inductively the member 1. The heating is stopped when the member is heated up to the hardening temp., then a solenoid valve is opened to feed cooling water through a cooling water supply port 2b into the coil 2 so that the cooling water is injected from an injection port 2a to the member 1 to cool quickly and harden the member. The fillet part 1a in the step part is difficult to heat and is not heated up to the hardening temp. at times and therefore the temp. measuring element 3 consisting of the optical fiber is disposed to face the fillet part 1a and the light radiated from the fillet part 1a is measured by said element; the measured light is converted to a temp. by a converter 4 and the member is hardened by opening the solenoid valve when the temp. of the fillet part 1a attains the hardening temp. The generation of deficient hardness owing to insufficient hardening in the fillet part is prevented.

Title: Substrate potential supply circuit
Inventor: ISOBE SADAHISA
IPC: H01L27/04
Filed: 1990-09-21
Abstract: PURPOSE:To enable the substrate potential to be lowered immediately by a method wherein the title substrate potential feeding circuit is composed of the first-fourth control signals, the first-fourth N channel type MOSFETs (NMOST) and a driving capacitor. CONSTITUTION:In case the capacity division of the substrate S capacity and the node N1 capacity is neglected, the potential VN1 of a node N1 is subjected to transition between the ground level and the-¦power supply level¦ if the substrate voltage VS exceeds -¦power supply level-VT of NMOS1-VT of NMOS2¦. Next, the potential VN1 is subjected to transition between VT of NMOST2 and -¦power supply level-V1 of NMOST2¦ if the substrate voltage VS does not exceed -¦power supply level-VT of NMOS2¦ so as to transfer the capacity for lowering the potential of the substrate potential VS. Through these procedures, the time making the substrate potentials attain -¦power supply level-VT of NMOS1-VT of NMOS2¦ can be cut down.

Abstract: PURPOSE:To prevent a compressor from being interrupted in its operation upon starting of heating operation by providing a heat source side refrigerant cycle and a utilization side refrigerant cycle, and further providing a control device for opening a solenoid valve for a predetermined time upon the strating of the heating operation and the solenoid valve provide in parallel to a heating pressure reduction device. CONSTITUTION:A solenoid valve 13 is provided in parallel to a heating pressure reduction device 5, which valve is opened for a predetermined time upon starting of heating operation by a control device 14. Accordingly, the amount of pressure reduction is reduced to lower the exchanged heat (amount of heat absorption) in a heat source side heat exchanger 3 and hence lower the amount of exchanged heat (amount of heat dissipation) in a first auxiliary heat exchanger 8. Thus, high pressure can also be lowered. Hereby, a compressor is prevented from being interrupted, the high pressure being raised upon the strating of the heating operation.
